Paper Abstract

Presented is a description of a preliminary qualitative study of the effects of spherical particle scattering on the polarization of linearly polarized He-Ne laser beams. Data were acquired for various concentrations of particles (either 0.22 micrometers or 0.494 micrometers diameters) in filtered, distilled water. The effects of some physical parameters, such as the detector acceptance angle and cylindrical scattering volume container diameter, are demonstrated. In general, the larger the diameter particles used and the higher the particle concentrations the more the incident beam is depolarized. Increasing the path length traversed by the scattered beam greatly depolarizes the beam (i.e., larger containers and detector positions at depth).
